RAlSlN-SEEDER.

SPECIFICATION forming part of Letters Patent No. 641,939, dated January23, 1900.

Application filed August 1, 1899. Serial No. 725,744. (No model.)

To all whom it may concern:

Be it known that we, CARY S. COX and THOMAS E. LANGLEY, of Fresno, inthe county of Fresno and State of California, have in vented a new andImproved Raisin-Seeder, of which the following is a full, clear, andexact description.

One object of our invention is to simplify and perfect machines forseeding raisins, and particularly to improve upon the construction ofthe raisin-seeder for which application for patent was filed by Gary S.Cox January 28, 1899, Serial No. 703,678.

A further object of the invention is to provide a self-cleaning comb forremoving the seed from the impaling-roller and to construct strippersparticularly adapted to remove the seeded raisins from the impaling orcarrying roller;

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section through a raisinseeding machine havingthe improvements applied, the section being taken practically on theline 1 1 of Fig. 2; and Fig. 2 is a central vertical section through themachine.

The frame of the machine consists of two properly-spaced standards A,and in the upper portion of these standards the trunnions of aheating-roller B are mounted to turn in any suitable form of boxes. Theheating roller or drum B is hollow and steam is supplied thereto in anysuitable manner. The said press heating roller or drum B receives theraisins to be seeded as they come from a screen-trough O of any approvedconstruction. Just below the roller or drum B a crossbar or fixed shaft10 is located, extending from one standard of the frame to the other,and at the central portion of the frame of the machine a main shaft 11is mounted to rotate. This shaft 11 is provided with an impaling orcarrying roller 0', and said roller consists usually of a body 12,secured to the shaft in any suitable or approved manner, and serrated ortoothed disks 13, that are attached to the body 12 and are properlyspaced by washers 14. The impaling-teeth of the impaling-roller arespaced so as to exclude the seeds of the fruit, and elasticpressurerollers D, or pressure-rollers having an elastic surface, aregrouped around the impalingmounted on a shaft 16,which shaft is adaptedto revolve and is provided with suitable bearings located in thestandards A of the frame. The said shaft is provided with a series ofserrated or toothed disks 15, secured thereon by keys or otherwise, andthese disks 15 are spaced by means of suitable washers or collars 17,likewise secured on the shaft 16, as shown best in Fig. 2. Strippers arelocated between the serrated disks, and said strippers are of lessdimensions than the width of the collars or washers 17. Each strippercomprises a ring-like head 18 and a downwardlyextending shank 18*, andthe ring-head of each of the strippers is loosely mounted upon a collarorwasher 17 Thus the shaft 16 and the collars and disks carried therebymay revolve, but the strippers remain stationary. Each stripper isprovided with a tooth 19 at the central portion of its upper edge, andthese teeth have one surface curved and the other opposing surfacestraight, the straight surfaces of the teeth of the strippers facing theimpaling-teeth' of the impaling-roller as said roller revolves. Theteeth 19 of the strippers bear such relation to the impalingteeth on theimpaling-roller that the teeth of the strippers effectually remove theseeds from the impaling-teeth. The serrated disks 15 are of greaterdiameter than the exterior diameter of the ring-like heads of thestrippers; but the teeth 19 of the strippers project beyond the teeth ofthe disks 15, as shown in Fig. 2. The serrated disks 15 of the improvedcomb are entirely out of contact or possible engagement with theimpaling-teeth, the serrated disks 15 simply serving as cleaningdisksfor the teeth 19 of the strippers. The strippers of the comb E are heldstationary and in proper position by passing a rod 20 through suitableopenings in the shanks 18 of said strippers, as is shown in bothfigures, each stripper where it receives the rod 20 having a set-screw21. This construction and arrangement of the serrated disks out ofcontact with the teeth of the impaling-roller,with the strippers betweenthe disks, not only removes the seed from the impaling-roller, but theshort cap-stems on the raisins, the hard red berries, the nails, andother foreign matter are also effectually removed without injury to theimpaling-roller, so common in other machines of this class. Theprojecting teeth of the strippers pull everything desired to be removeddown to the serrated disks, and these disks in turn throw off the matterto be removed and keep the teeth of the strippers clean. Besidespreventing much injury to the teeth of the impaling-roller from theforeign matter present this construction and arrangement also preventsthe throwing 01f of a large percentage of good raisins,which happens inmachines where the serrated disks are arranged sufficiently close to theteeth of the impaling-roller to remove the seed and foreign matter.

Pendent strippers 22 are employed to remove the seeded fruit from theimpaling-roller. Each stripper 22 consists of a hook-shaped head 23 andan elongated body 22 The heads 23 of the fruit-strippers are made toreceive the fixed rod 10, while the body portions 22 of thefruit-strippers extend downward between the impaling-disks of theimpalingroller, the forward edges of the body portions of thefruit-strippers being preferably curved to conform partially with thecylindrical surfaces of the spacing-washers 14 of said impaling-roller,and the rear lower edge 23 of the body portion of each fruit-stripper22is rounded off in an upward direction. When the fruit-strippers are inposition, as the impaling-roller revolves the lower ends of thefruitstrippers engage with the fruit that lies between theimpaling-disks and force the seeded fruit out from the roller. Thefruit-strippers 22 are adjustable with reference to the impaling-roller0, preferably by passing a bar 24.- through suitable openings in thestandards A of the frame, the said bar entering recesses 25, formed inthe rear edges of the said fruitstrippers just below their heads 23, andthe locking-bar 24 is held in suitable position by set-screws 26.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a machine for seeding fruit, animpaling-roller, a comb consisting of serrated disks mounted to revolveadjacent to the periphery of said impaling-roller, butout of contactwith said roller and the seeds carried thereby, and strippers heldstationary between the said disks and each provided with a projectionextending in direction of the teeth of the impaling-roller and adaptedto engage with the seed to be removed from the said roller, saidserrated disks of the comb serving as cleaners for the strippers, as andfor the purpose specified.
